To all whom t may concern:

Be it known thatl, HERMAN Gnlarin, ot New York city, in the county and State of New York. haveJ invented a nen7 and useful the following is a speeiiication.

The object oi this invention is to provide a simple `mechanical movement by meansj-O which a driven member forming part thereo ot may be shifted back and forth with a quick snap movement by means oit a driving member that is actuated, or intended to be actuated. by means which does not of itself impart a quick snap movement to the driven i5 member.

My invention consists primarily in a mechanical movement :tor accomplishing the above and other objects and in the preferred driving member mounted o move back and :torth to a limited extent, va driven member mounted to move back and forth to a limited l,sortent and a spring connecting said meinberswhich spring oscillates on an axis perpendicular' to the y 25 direction of movement of one of said members.

@ther eaturesvoif' my invention will be pointed out below.

ln the drawings: Figure 1 is a plan view so of my mechanical movement embodying my invention; Fig-@is a section' on .line 2-2 of ig. l; and Fig. 3 is a modiiication described below.

Having reference tothe drawings A is a strip ci? metal bent to provide a pair of wings a, which support and guide a driving member B and having a central recess or pocket a to receive a driven member C. The traine A may be 4:0 Afastened to any suitable supporting fixture D by means of screws d, d as shown. At the middle of recess a the frame A is provided with a stud 0,2 by means of which the driven member is `pivotally held within formed at its ends with two stop shoulders a3 and at eooperating, respectively., with butmcnt sur-l limit the swinging or osot' member Con stud a2.,

faces c3 and 4c* to cill ating movement with'. arms c connected by links 02 with the device or devices that are to be\controlled and actuated through the mechanical movement:

sa The drivingmember B isherein shown as as shown, be provided serial no. 87,101.

zereciprocating bar formed with tivo pairset hooked lugs Zw, and b', b embracing wings z so as to hold said driven member in place on frame A with provision for limited endwise movement thereon, the engagement of lugs Z) and b with shoulders a5 and a serving to limit the movement of member A in both directions. i

The member B is formed upon its under side with a recess bl into which a hole bs opens. Une of the arms c of member C is likewise formed upon its under side with a similar recess at 05 and c opening into the same. Through the holes bs and 06 extend the ends ot a bow-spring E whose extremities are formed with hooks c which hold said ends in engagement with the two members and against accidental dishave shown said member as connected by a pin f and slot b9 with an actuator F- which niay be a connecting rod driven at its opposite end by a crank (not shown).

in the drawings the connecting rod and member B are shown at the limit oit' their movements toward the right. When connecting rod F moves toward the left the pin f carries member B with it and the movement of the latter toward the left carries the end a2 of spring E toward pivot stud 'a2 thereby either increasing the normal stress eti-spring E, if it has any, or putting said spring under increasing stress as the end e2 travels up to stud a2. As the end e2 passes beyond stud 1,2 the spring is under maximum stress and upon reaching a position upon the opposite side of stud a? the direc- .tion of the pressure of the end e3 of spring E on member C has been shifted to such an angle that said pressure acts to swing memn'ber C in the direction o'l the arrow-and this swinging movement of member' C acts to shiftthe direction ofthe pressure of end e2v y on member B to such an angle as to accelerate the movement of member kick the latter to the extreme limit of its movement toward the left, the slot b pro- B and viding for relative movement at this time between member B and actuator F. Itwill be clear that this racing or jumping movement of member B takes place practically simultaneously with the start of the movement of member C and, in conjunction with the movement of member C, suddenly increases the effective pressure of spring E on member Thus immediatelyv upon the start of member C the member B is jumped forward, the eli'ective pressure of spring E is increased and the movement ofinember C accelerated from the very start thereof. In this way the driven member C is shifted from one position by a quick snap movement free of any creep, the engagement of the abutment surfaces c3 and c* with the stop shoulder a3 and a* limiting the movements of member C in both directions. The operationr of the parts in snapping member C in the opposite direction, that is, back to the position shown in the drawing is merely the reverse of that described and will be clear without further description.

The mechanical movement shown. in Fig. 3' operates in the saine fashion as the movement shown in Figs. l. and 2 and with one exception its construction is the same. This exception is that while the bow spring E of Figs. l and 2 is upright, the body ofthe corresponding spring E of Fig. 3 is bent down into parallelism with members B and C for economy of space.

What 1 claim is:

1. A mechanical movement comprising a driving member, a driven member and a spring connecting said members which spring oscillates on an axis perpendicular to the direction of movement of one. of said members.

2. A mechanical movement comprising a driving member, a driven member and a spring connecting said members which spring oscillates on an axis perpendicular to the direction oit-movement of said driving member.

3. A mechanical movement comprising a Y driving member, a driven member, and a spring connecting said members which spring oscillates on an axis perpendicular to the direction of movement of both of said members.

4. A mechanical movement comprising a a driven member, and a. bow spring connecting said members which spring oscillates on an axis perpendicular to the direction of movement of one of said members.

5. A mechanical movement comprising a driving member, a driven member, and a spring connecting saidy members and put under stress in a plane at a right angle to one of said members and when released osin engagement with said member, said driving member actuating the driven member by .means of said spring.

8. A mechanical movement comprising a drivingmember, a driven member, a spring connecting said members which spring oscillates on 'an axis perpendicular to the direction of movement of one of said members; and means to limit the movement of the driven member.

9. A mechanical movement comprising a driving member movable back and forth, a. driven member movable back and forth, and a spring connecting said members that is os cillated by the driving member in a direction parallel with the direction of movement of the driving member to operate the driven member.

10. A mechanical movement comprising a driving member and a driven member bothl movable back and forth in parallel planes and a spring connecting, and carried by, said members and oscillating on an axis perpe1idicular to the direction of movement of both of said members, the drivenl member, when moved in one direction acting rst to put the spring under stress and .thereafter to cause said spring to snap the driven member from one extreme f its movement to the opposite extreme.

11. A mechanical movement comprising a driving member and a driven member both movable back and forth in parallel planes and a spring connecting, and carried by, said members and oscillating on anaxis perpendicular to the direction of movement of both of said members, the driven member, when moved in one direction acting first to put the spring under stress and thereafter to cause said spring to snap the driven member from one extreme of its movement to the opposite extreme and said spring serving to normally hold each member at the limit of its movement in one direction or the other.
